Rust Mesh-Library for point-interpolation

[michelk]

Hi,
I'm very new to Rust and looking for a Rust Mesh Library to extract (interpolated) point data from a surface mesh (indexed face set with x,y,z-vertices).

Background:
I have a triangulated surface-mesh with hydraulic-simulation-results-information per face.

  struct Coordinate {
      x: f64,
      y: f64,
      z: f64,
  }
  struct TriangleIndices {
      v1: u32,
      v2: u32,
      v3: u32,
  }

  pub struct Mesh {
      coordinates: Vec<Coordinate>,
      topology: Vec<TriangleIndices>,
  }

Now I would like to extract for an arbitrary set of x,y-points

• (a) face-index for each point and
• (b) interpolated z-elevation based on face-plane made up by mesh-vertices.

Do you think your mesh-library could help for this application or could you give an advice which library to use instead or should I handroll the process (Point -> FindFace -> Face -> Plane -> Interpolation)?

Thanks,
Michel
